Topic: Screened bottom board or solid? (Read 3543 times)

Just wondering if I really need to replace my screened bottom board with a solid one for winter. I have both, but of course it's a heavy annoying job - two deep supers above, both pretty full. The screened board I use has a slide-out drawer with a white liner (to see mites, I guess). I could stuff some insulation into the opening underneath the sliding drawer to close up the opening. Would that be enough or should I really haul my husband down to the hive to help me with the heavy lifting? I'll be wrapping the hive in tar paper or some other wind-break covering and putting a bit of insulation on top of the inner cover as well. I'm in central Ontario, so yes it gets cold here.

I live in TN and it doesn't get nearly as cold here as where you live but I close my SBBs. Because it doesn't make sense to leave that much open space under the hive. Take the floor out from under your house and see how much more energy it will take to keep your house as warm as with a floor. But to be fair alot of beeks around my area leave them open. The same beeks will say be sure and leave 50# to 60# of stores per hive and my bees don't use half that. The last two club meetings had speakers who promoted leaving them open. I wouldn't unstack but would slide a board under if you decide to close em.

So what I did last winter - which was, to be honest, not a typical winter - was to use a solid bottom board. I had two deeps for the colony, then the inner cover, then a third deep (but with no frames in it). I left the inner cover opening a bit open but packed some insulation around it so that moisture could escape, while hopefully maintaining the colony's warmth. Put the telescoping cover over top and wrapped all three boxes with tar paper and put a mouse guard over the front entrance. I don't think I even reduced the entrance at all. Whatever it was, it worked - but as I said, last winter was not at all our typical cold winter.

So let's say I stuff insulation into the space under the sliding drawer in the screened bottom board to keep the cold out from underneath. All else will be the same: wrap the hive, insulate over the inner cover, keep an opening in the inner cover, no upper entrance. I'm just trying to avoid having to replace the bottom board, that's all. I'm being lazy (I know).

I don't like this whole winter business. It's stupid and a pain.

Bye poly hives. You need not do those odd things ans play with those boards.

don't your screened bottoms have slots to insert a board? you should be able to cut some thin plywood to fit, or use some kind of plastic....mine have thin sheet metal inserts. i like those. they don't warp.

wet, cold, bees die faster, but cold bees die too. the idea that cold won't kill bees is a bit nuts if you give it a good thought.

.....The greatest changes occur in their country without their cooperation. They are not even aware of precisely what has taken place. They suspect it; they have heard of the event by chance. More than that, they are unconcerned with the fortunes of their village, the safety of their streets, the fate of their church and its vestry. They think that such things have nothing to do with them, that they belong to a powerful stranger called “the government.” They enjoy these goods as tenants, without a sense of ownership, and never give a thought to how they might be improved.....

If cold doesn't kill bees then why do beeks who live in northen areas lose more hives in winter then beeks in say Florida or Georgia?Why would beeks waste time and money on insulated hives and heating hives? What a waste, just open up the bottom and they will be fine.

Screened bottom or not? Do you keep your basement windows open all winter? Would it make sense to leave them open to “ventilate” your house?

To me, leaving big holes in a house or a beehive defeats the purpose of insulation and winter protection. My poly hives have NO big holes anywhere in them during the winter; just a relatively small entrance. If the bees knew how to open and close doors, I wouldn’t even have the entrance hole :)

Like I said, there's a slide-in drawer so it's not open open. I wouldn't leave them completely open for the winter - just wondered if there's a real difference in a screened bottom board that's been closed up vs. a regular solid board.

On a slightly different note, I just came back from looking at the hive and they are bringing in a TON of pollen! It's nearly the end of October in Ontario - I thought that was over. I think they're getting it from the late asters. Amazing, really. Quite a few wasps around the hive too, but the bees are keeping them out so it's ok.
